In this high-stakes, edge-of-your-seat thriller, a thin thread of survival separates a teenage kidnap victim from her only hope: a compassionate, steady voice on the other end of a cell phone marshaling all the resources she can to find her.

Veteran 911 Emergency Call Center operator Jordan has the kind of job that's not for the faint of heart: navigating the public's distress in order to save lives. But when a young woman's frantic report of a prowler ends tragically, Jordan is devastated. Reassessing her life, Jordan wonders if perhaps she's experienced her last fraught-filled phone call. With a supportive cop for a boyfriend, maybe it's time to step back, enjoy life, and teach others the ins and outs of her high-pressure profession.

That lifeline to strangers isn't over yet, though. When average American teenager Casey, is abducted by a serial killer, she manages to place a 911 call from the trunk of the killer's car.

Jordan, leading a group of new recruits through the massive Call Center operation, is in earshot of the call. It's an all-too familiar scenario for this experienced public servant, but before long, Casey's situation reveals itself as eerily, shockingly familiar. There's only one thing Jordan can do: take charge in a way she's never done before. She must turn Casey into a partner in helping them track down the killer, and prove that this call is Jordan's calling.
